Toroidalcore
Toroidalcore is a category of magnetic core used in inductors and transformers, defined by its doughnut-shaped geometry. The torus shape encloses the magnetic flux, creating a closed magnetic circuit that minimizes flux leakage and confines the magnetic path within the core material. In practice, windings are placed around the torus, and the assembly is often clamped or potted to maintain winding integrity. The term is sometimes used as a shorthand for toroidal-core inductors and toroidal-core transformers.
Advantages include a high inductance-to-volume ratio, low electromagnetic interference, reduced running noise in transformers, and a
Materials and construction: common core materials include ferrites for high-frequency applications and powdered iron for broader
Applications: widely used in switching power supplies, audio equipment, RF filters, and impedance matching networks. They
